Further, the center server 83 receives the user ID based on the information acquisition unit (acquisition means) 35 for acquiring the vehicle ID, the key ID, and the authenticated information, and the personal ID and the authenticated information stored in the DB (management unit) 32. 5 is provided with a personal authentication unit (authentication unit) 36 for performing personal authentication and an authentication result transmission unit (transmission unit) 37 for transmitting an authentication result.

  9 and 10 is replaced with doorknob fingerprint authentication (S51), face authentication (S54), and engine start switch fingerprint authentication (S56) in the biometric authentication system 1 shown in FIG. Then, the personal authentication process is performed on the center server 83 side (S41, S45, S48 in FIG. 10). That is, the biometric authentication system 8 acquires the biometric information of the user 5 and uploads it to the center server 83 (S33 in FIG. 9, S44, S47 in FIG. 10), and performs remote authentication on the center server 83 side.

  Operations other than those described above in the biometric authentication system 8 are the same as the operations in the first embodiment.

  According to such a biometric authentication system 8, the user 5 is authenticated in the same manner as the biometric authentication systems 1 and 6 in the above embodiment, and when the user authentication is established, the user 5 can start the vehicle 82. It becomes possible.

  According to the biometric authentication system 8 according to the present embodiment, the user 5 is authenticated based on the personal ID of the user 5 stored in the DB 32 and the authentication information of the user 5 acquired by the information acquisition unit 35. . Here, since the personal ID of the user 5 is stored in the DB 32, high security is ensured. In addition, when the use operation of the user 5 to the vehicle 82 is detected by the key detection unit 21, the information to be authenticated is acquired by the information acquisition unit 35 and the personal authentication is performed by the personal authentication unit 36. There is no need to perform an operation for accessing the DB 32, and it is only necessary to provide the authenticated information to the information acquisition unit 35. Therefore, the personal authentication can be performed with a small number of operation procedures while ensuring high security.

  The preferred embodiment of the present invention has been described in detail above, but the biometric authentication system according to the present invention is not limited to the above embodiment. In the above-described embodiment, the vehicle engine start permission control is performed when the personal authentication is established, but other control may be performed such that the object to be used can be used according to the authentication result. The vehicle door lock may be unlocked when the identity authentication is established. Moreover, although the said embodiment demonstrated the case where a utilization target object was a vehicle, what kind of thing may be used as long as it authenticates the person using biometric information, for example, a residence, ATM, a personal computer etc. There may be.

  Moreover, in the said embodiment, although approach of the biometric authentication subject was detected based on the positional information on the mobile phone which the biometric authentication subject possesses and the location information of the vehicle, the utilization target is a fixed object such as a residence.
